Which has a greater area, a square with sides that are x - 1 units long or a rectangle with a length of x units and a width of x - 2 units?

Area of square = a^2...where a is the length of 1 side
A = (x - 1)^2
A = (x - 1)(x - 1)
A = x^2 - 2x + 1

Area of rectangle = L * W
A = x(x - 2) = x^2 - 2x

The greater area would be the square <==

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
